釋禪波羅蜜次第法門 6.154

6.154

復次，前虛空處破色故說空，識處破空故說識，說識為有想，不用處破識故無識，說無識為無想。今此定破無所有，說非無想，故言非有想非無想。此定於世間中沈浮等故，智、定、空、有均平，是定安隱，於世間中最為尊勝，等智所不能破，故數人言：「一常有漏。」

Furthermore, previously, the base of empty space refuted form, and so spoke of space; the base of consciousness refuted space, and so spoke of consciousness, calling consciousness 'having perception'; the base of non-employment refuted consciousness and so was without consciousness, calling the absence of consciousness 'non-perception.' Now this absorption refutes nothingness and speaks of 'not non-perception'; therefore it is called 'neither having perception nor non-perception.' In this absorption, sinking and floating are equal in the mundane realm, so wisdom and concentration, emptiness and existence, are balanced. This absorption is peaceful and secure, the most supreme in the mundane realm, and cannot be broken by conventional wisdom; therefore the Abhidharmikas say: 'It is always defiled.'
